Great shot, Margaret! First of all, the color match between the window & her sweater carries the eye nicely. Then, over to the woman on the poster who almost looks like the Russian woman...you wonder whether her hair is also up in a bun...Yet, the obvious class difference between the two women says of course not... The model's skin on the poster recalls the sweater and window too... And the replication of blues & reds throughout. All these little things come together in a wonderful composition.
